Cobbler vs Redocly: at a glance
What is Cobbler?
Cobbler's 3.3 backport branch ships Leap 16 and Agama support, then has to re-cut the release
Cobbler's public releases are all 3.3-branch backports, and the branch just had its most substantial drop in nearly two years. 3.3.8 added import and manage support for openSUSE Leap 16 and its Agama installer, interactive and automatic XCP-ng network installs, and basic Python 3.13 support. It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was fixed. Before that pair, recent history is dominated by the CVE-2024-47533 admin-API bypass, patched on both 3.3 and 3.2.
What is Redocly?
Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.
Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.

Cobbler's 3.3 backport branch ships Leap 16 and Agama support, then has to re-cut the release
◆ Current state
Cobbler's public releases are all 3.3-branch backports, and the branch just had its most substantial drop in nearly two years. 3.3.8 added import and manage support for openSUSE Leap 16 and its Agama installer, interactive and automatic XCP-ng network installs, and basic Python 3.13 support. It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was fixed. Before that pair, recent history is dominated by the CVE-2024-47533 admin-API bypass, patched on both 3.3 and 3.2.
◆ Where it's heading
The branch is tracking new installer and distro ecosystems rather than winding down: Agama and XCP-ng are current targets, and Python 3.13 support keeps the package installable on newer hosts. Release engineering is the weak point, and the entries show why - SHA-pinning GitHub Actions inside CI is what broke the publish step, at the cost of a same-day defunct-and-replace. Feature work continues to arrive as rollups from main rather than as branch-native development.
◆ Prediction
Expect the next 3.3.x tag to be another backport rollup, with CI hardening following the 3.3.9 failure. Whether the main line cuts a 3.4 is not something these entries show.

Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.
◆ Current state
Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.
◆ Where it's heading
Two threads run together: an agent inside Reunite that does recurring docs work (feedback and discovery) and is gaining scheduling and scoping controls, and enterprise plumbing such as SCIM scale, Git token rotation and permission fixes. Last week's configurable docs MCP server points the same way, with Redocly adding AI surfaces and making them configurable in redocly.yaml.
◆ Prediction
Expect more reunite.agent duty types or options in @redocly/config, and the experimental diff command moving toward a documented API-change check.
